Newest Macbook Air Gaming Performance?

Yo, so I want to buy the 13.3 inch Macbook Air, and I was wondering how it performs with gaming and videos and such. I know that some of you will say, "oh, why the hell would you buy a mac, especially a laptop, for gaming? There are such better computers to buy!" My answer to that is that I used a macbook pro for entire school year(My school provided) and I got really used to playing on it. So much so that I can't go back to a desktop. So the question I have, how does it perform? I've looked at the specs, but I really don't know too much about computers and stuff, so I don't really know what a lot of it needs. I mostly play Minecraft(surprise surprise) but I also play some other games, but all the other games take less power to play without a lot of lag and such. I also watch a lot of YouTube. I'm talking, a lot. The Macbook Pro easily handled my games and my youtube, so maybe I could find my answer comparing the specs of the two, but I think it would be better to get an answer from someone who actually knows computers. And also, please don't waste your time trying to convince me to buy some other laptop, unless the laptop is extremely efficient and costs roughly the same or less than the macbook air. Thanks in advance to anyone that can answer my question!

Added (1). By 'newest macbook air', I guess I mean the one from 2013. The one that released in 2013 that costes $999 for 13.3 inch screen.

Yes a macbook will play those games

but you can get a chromebook, install linux, and play what game you want for 1/4 the price

4GB's of ram is pretty low for gaming.

You will probably be able to play minecraft or some other games are derp low settings.
